Read: If COMRV[1:0] = 00
Write: If COMRV[1:0] = 00 and DBG is not armed.
This register is visible at 0x0027 only with COMRV[1:0] = 00. The state control register 1 selects the
targeted next state whilst in State1. The matches refer to the match channels of the comparator match
control logic as depicted in
the comparator enable bit in the associated DBGXCTL control register.
The priorities described in
final state has priority followed by the match on the lower channel number (0,1,2). Thus with
SC[3:0]=1101 a simultaneous match0/match1 transitions to final state.
